When you become more advanced at your LD skills like you are, yes, this seems to happen to a lot of us. I have experienced some involuntary hallucinations (illusions, technically), not recognizing everyday objects for a second, or forgetting I have a physical body that needs to urinate because of time dilation. When you wake up after having a ten-year dream in one night, it takes awhile to get re-oriented to this world.
I don't really ask myself if I'm dreaming or not anymore, because I think maybe all planes are different types of dreams (physical/astral/dream planes) and this waking life is another serial dream where the rules are different compared to the other planes. So, now I ask myself, "Which world am I in?"
I call this phenomenon you experience, The Bleed Over.
